C1 Haunt/y link 42 is 20 and provided The fulcrum is socket-like casing 15.

movably supported in a seat 36 onpthe side of the valve Below the fulcrum 35, is-a cam 37 carried by therock-shaft 38. The cam is arranged inn bearing 39, as shown in Fig. V. A friction reducing roller 40 is provided 38 is provided with an arm,,eil to Whichthe pivoted at 43. The outer-endof this link-issupported by the supporting link 4a, the lower-end of which is-engaged by thestem of the'valve 10, so thatwhen thepiston valve '10 isectuatcd-by the water, the-cam 37 isactuatedto raise the fulcrum 35, thus'rendering the operating connections for the thermostat'to the gas valve operative. Thelever-B is operatively associated with the stem 4'6 of the gas valve 27, the stem being provided with a shoulder 48 against which the bearing washer l9 rests. The le'vcr'j34-is slotted at 50 to receive the valve stem, See'i ig. VIII. The cam 37' is returned to its normalposition by means of the spring actuated plunger 51 which engages the link 44. The plunger 51 is arranged through the end of the cap member with a diskilze head against which the spring 52 bea rs. lVith the parts thus arranged, when the water valve is returned to its initial position before the discontinuance of the floi'ot' water to the heater, the plunger returns the link ll to its initial position and through the connection described, the fulcrum adjusting cam. With the parts thus arranged, when the Water is drawn from the heater, the unbalancingof the pressure opens the valve 10 and simultaneously actuatcs the fulcrum member 35 so that, when the temperature of the water passing through the heater is member, have been below a predetermined degree, the gas valve is opened through the thermostat. The thermostat, with its connections thus positioned, operates to contr ol the gas valve in the usual manner. hen {the drawing of water from the heater cea s, the gas valve is immediately closed by its springs, owing for holding it to the fact that the means open,namcly, the thermostht and't'ulcrum returned to normal position.

Tlie plunger 51 and the valve stem are provided with cap-like bearing members 53 between which the lower end of the swinging link 44 is arranged.

I am aware that very considerable variation from my invention in structural details are possible without departing from my invention, but as such variations will undoubtedly be readily understood from the disclosure made by those skilled in the art to which this invention relates, I have not attempted'to illustrate or describe the same herein. I desire to be understood as claiming my improvements specifically in the form 'illustrated,as well as broadly Within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is l. The combination with a water heater comprising a water container and heating means, of a fuel. valve, 21 Water valve, means for normally closing-said valves, a'thermostat, operating-connections for'said thermostatto said fuel valve-comprising a lever, a movable member constituting a=fulcrum for said lever when, actuated by said thermostat, a seatfor said member, a cam by which said member is supported in its said seat, a rock shaft on-which said cam ismounted, an arm on said rock shaft, a link actuated by said Water valve connected to'said arm, and a springfor returning said cam to its initial position.

means, of a fuel valve, a water valve, means for normally closing said valves, a thermostat, operating connections for said thermostat to said fuel valve comprising a. lever, a movable'memb'ci' constituting a fulcrum for said lever when actuated by said thermostat, a seat for said-member. a cam by which said member is supported in its said scat, a rock shaft on which said cam is mounted, actuated by saidwater valve, and a. spring for returning said cam to its initial position.

'ihe combination with a water heater comprising a water-container and heating means, of a fuel valve, a water valve, means i or normally closing said valves, :1 thermostat. operating connections for said thermostat to said fuel valve comprising a lever, a movable member constituting a l'ulcrum for said lever when actuated by the thermostat, and cam arranged to act on said member, said cam being actuated by said water valve.

i. In a water heater, the combination with a water heater comprising a water container and healing means, of a fuel valve, a water valve, means for normally closing said valves, a lever acting on said fuel valve, 'a thermostat mechanism including a member acting on said lever, a movable member acting on said lever and constituting a ful crum there-tor when the same, is acted upon by said thermostat, and operating connections for said water valve to said-movable member whereby the same is actuated by the opening of the valve, the combined action of the water actuated valve and thermostat eing required to open the gas valve.

The combination of a water heater comprising a water containing and heating means, of a fuel valve, a water valve, a thermostat, operating connections for said iaaaeea o thermostat to said fuel valve comprising a lever, and a movable member coi'istituting a fulcrum for said lever when actuated by said thermostat, said movable member being actuated by said water valve whereby the thermostat is operative to open the gas valve only when the water valve is opened.

6. A controlling device for water heaters comprising in combination, a water valve, a gas valve, meansfor normally closing said .valves, a thermostatic control means for said gas valve comprising a lover, a inovable member constituting a fulcrum for said lever when it is actuated by said thermostatic controlling means, and operating connections for said water valve to said movable member. v

7. The combination of a water heater com prising a water container and a heating means therefor, a thermostatic controlling means for said heating means governed by the water of the heater and comprising a lever member, a member enacting as a fulcrum when said lever member is actuated by said thermostat, and water actuated member having operative connection with. said movable member. v 4 v 8. A controlling device for the heating means of water heaters, comprising a water container and heating means, a gas valve, a

thermostatic controlling means governed by the water of the heater and comprising a lover, a water actuated member, and a member actuated by saidwater actuated member constituting a fulcrum for said lever when the same is actuated by said thermostat whereby said thermostat 'and water actuated means coact in operating the gas valve. i

9. The combination with a water heater comprising a water-container and heating means, of a water .valve, a gas valve, means for normally closing said valves, a thermostatic controlling means for said gas valve comprising a thermostat lover, a movable member constituting a fulcrum for said lever when actuated by the thermostat, and operating connections for said water valve to said member whereby said member is moved to support the lever in. operative position when the water valve is opened. E

10. The combination with a watenheater comprising a water container and heating means, of: a fuel valve, a water actuated port the lever in operative position when the water valve is open.

11. The combination of a water heater comprising a water container and heating means therefdr, of a thermostatic controlling means for said heating means governed by the water of the heater andcomprising' a lever member, a movable member coacting with said lever member as a fulcrum when said lever member is actuated by the thermostatic means, and a water actuated memher having operative connection with said movable member whereby the-heating means is controlled by the combined. action.

12. In an automatic heater, the combination. with a water heater comprising a water container and heating means, of a gas valve therefor, a power transmitting lever ar-' ranged to operate said gas supply valve, and two power applying mechanisms for said lever, each adapted to act as the lever-fulcrum'when the other is in operation, one'oif said mechanisms including a thermostat and the other a'water actuated motor, the thermostat being efi'ective in opening the valve only when the motor actuated member is actuated. v

13. In an automatic water heater the combination of a water heating conduit, a burner, a gas supply valve therefor, a power transmitting lever arranged to operate said gas valve, two power applying mechanisms movement of either thevvater motor or the thermostat varies the effective action of the other upon said valve I In witness whereof, l have hereunto'set my hand and seal in the presence of two witnesses.
